Title: Improvements in or relating to knitted fabric and methods of knitting
IPC: D04B9/54
Filed: 1943-02-08
Abstract: 564,391. Knitting. HEMPHILL CO. Feb. 8, 1943, No. 2063. Convention date, Feb. 9, 1942. [Class 74 (ii)] In knitting accordion fabric upon a machine in which one yarn is supplied to all the needles at one feeder and a second and finer yarn is supplied to alternate needles only at a second feeder, the second yarn 10 is drawn by the alternate needles 17, 19 over the nibs of the sinkers 14, 20. The floats or sinker loops 22 connecting adjacent needle loops 4, 6, 8 of the second yarn are thus caused to rob the yarn from these needle loops so that the rib appearance is accentuated. A greater tension may be applied to the second yarn than to the first yarn. The knitting cams at the second feeder may be arranged to cause the needles to draw shorter loops at the second feeder than at the first feeder.

Abstract: 377,660. Submarine mines. SOC. ANON. PIGNONE-OFFICINE MECCANICHE E FONDERIA, 2, Via della Fonderia, Florence, Italy. Jan. 22, 1931, No. 2169. Convention date, Jan. 22, 1930. Void [Published under Sect. 91 of the Acts]. [Class 9 (ii).] Relates to submarine mines which when thrown into the sea sink to the bottom and then rise to the appointed depth, and which during this operation are protected against heavy external hydrostatic pressure by internal gaseous pressure. According to the invention, the internal gaseous pressure is produced by gases generated gradually under control of an hydrostat, for example by acetylene gas generated from carbide d in the anchor b by admission of sea water thereto through a valve g, which opens automatically when the external pressure is higher than the internal pressure. The acetylene passes through a pipe e to the mine casing a, and when the mine casing rises from the anchor the upper part of the pipe e, which was connected to the lower part by a telescopic joint f, is closed by a valve i tripped by the depression of a bolt k by the tension of the mooring cable, so that escape of gas is prevented. Undue inside pressure is relieved by a safety valve h.

Title: Improvements in or relating to furnaces and methods of operating the same
IPC: C01B21/32
Filed: 1950-01-27
Abstract: In the manufacture of nitrogen oxides by passing a mixture of nitrogen and oxygen, e.g. air, through a regenerative pebble bed furnace wherein the gaseous mixture is passed through a first preheating pebble bed, a reaction zone heated to nitrogen fixing temperatures and a second pebble bed to chill and stabilize the nitric oxide formed and in which the direction of flow is periodically reversed, the pebbles are passed periodically or p continuously into and out of the beds during the operation of the furnace.  In the preferred apparatus, Fig. 2, the regenerative furnace is a unitary roof structure extending over both beds and the reaction zone.  The reaction zone 110 is formed between a roof 114 composed of refractory bricks supported on a tubular water-cooled structure 115 and a base 112 formed of refractory material such as rammed magnesium oxide.  On either side of the reaction chamber are pebble-filled spaces 121 and 122.  The walls of the pebble chambers are formed by superposed layers 123 of refractory bricks that slant towards the centre of the furnace at the angle of repose of the pebbles and rest on base plates 125 and 126; successive strata of refractory material 123 are separated by metallic baffle plates 152 which terminate flush <PICT:0718011/III/1> <PICT:0718011/III/2> with the inner surface of the chamber 121.  The baffle plates may be made of differing material depending on the temperature to be encountered in the zone 121; thus the lower plates 153 may be of stainless steel, the middle ones of a metal alloy and the upper ones are made of an iron free material such as nickel.  Pebbles are fed to the two chambers 121, 122 from pebble reservoirs 141, 142 to flow between the edge of the roof 114 and the uppermost refractory stratum of the chamber wall, the pebbles assuming their natural angle of repose as they enter the beds.  Pebbles may be withdrawn from the bottom of the chambers by rocking arms 131 and 132.  In operation air is supplied alternately through pipes 161 and 162; for example is passes up through the hot chamber 121 and through the reaction zone 110, heated by the injection of fuel from nozzles 160; the nitric oxide formed is stabilized by passing through the bed of pebbles 122 which is cold. When bed 122 becomes hot and 121 becomes cold the direction of the passage of air is reversed.  An alternative means of withdrawing pebbles from the bed is shown in Fig. 5 where a sheet 215a is oscillated about a crank 217 whereby quantities of pebbles from bed 211 are brought to the left by the oscillating plate and during the movement to the right of the plate the pebbles withdrawn are forced over the left edge of plate 215a by further pebbles which have by then dropped from chamber 211.

Title: Improvements in or relating to travelling wave amplifier discharge tubes
IPC: H01J23/30
Filed: 1949-01-28
Abstract: 682,506. Travelling wave-tubes. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Jan. 28, 1949 [Feb. 10, 1948; June 28, 1948], Nos. 2454/49 and 2455/49. Class 39(i) In a travelling wave amplifier tube dielectric lossy material is in direct mechanical contact with, and wholly or partly surrounds, the helix. The lossy material is preferably localised at the centre of the helix. In one form, Fig. 1, the helix H supported by quartz rods Q is provided at its central region with sections M of lossy dielectric material such as slate or comprising ceramic substances. In a modification, Fig. 4 (not shown), the ends of the lossy material are bent away from the helix so that the characteristic impedance varies gradually and wave reflections are minimised. Alternatively, the ends of the lossy material are tapered, Fig. 5 (not shown), or the expedients of Figs. 4 and 5 may be combined. In another form, Fig. 2 (not shown), the helix is surrounded by a dielectric tube, e.g. of glass or ceramic. In a modification, Fig. 3, further attenuation is obtained by a resistance layer R of metal or graphite, formed as a coating on the inner surface of the dielectric tube C, and wound as a helix of the same pitch as the wave-propagating helix H. The resistance layer R, which must not touch the helix H, may be formed by evaporating a wire stretched along the axis of the tube, the helix H shielding the portions of the tube wall C where the layer R is not required. A prior art construction in which the quartz support rods of the helix are coated with a thin layer of colloidal graphite at the centre of the helix is referred to; the resistance of the coating must be greater than 500 ohms per millimetre. A helix with uniform attenuation along its length, e.g. made of high loss material such as iron, is stated to be undesirable. Further attenuating sectors of material may be added during manufacture to obtain the best results. There may be a plurality of localised attenuation regions along the helix. The Specification as open to inspection under Sect. 91, states that the lossy material need not be in contact with the helix. This subject-matter does not appear in the Specification as accepted.
